This invention relates to carbon transfer sets for use in connectionwith. typewriters, calculating and' tabulating machines and ofcerecording machines, of a. similar nature wherein a plurality ofsuperposed record sheets are used with the sheets of the carbon transferset suitablyinterleaved.

It is a general object of the invention to provide a carbon transfer setof the class mentioned having improved features of construction adaptingit for more effective use in connection with the positioning of thecarbon or transfer sheets in interleaved transfer relation with recordstrips of the long continuous traveller type and. which, moreover, is ofsuch a simple structural nature that it may be expeditiouslymanufactured with a minimum o-f production costs..

A further object of the inventionis to provide a carbon transfersethaving an improved structure and arrangement of the transfer sheetsupporting elements whereby it may be conveniently used in connectionwith long continuous record strips of the fan-folded type as well aswith long continuous record strips which are separate and distinct fromeach other.

Other objects of the invention will be in part pointed out inthe-detailed description below of an illustrativev but preferredembodiment of the invention, and will be in part obvious in connectiontherewith.

According to the invention the transfer set comprises a backing sheethaving a holder part and a series oftransfer sheet supporting members,which may be blades, hingedly connected to a side margin of the holder,so that they can be swung about their hinges clear of the holder.

Each supporting blade or the like serves as a holder for a carbon sheet,the latter being attached alongits top edge to the blade. The blades maybe superposed or otherwise s arranged that the carbon sheets aresuperposed for transferring inscriptions to the record sheets or strips.Preferably each blade extends completely across the carbon sheet so thatthe latter is rigidly supported over its full transverse length, but thewidth of the blades and the corresponding carbon sheets may vary in anygiven transfer set. The `carbon sheets are of any desired length andpreferably all the sheets of the set 0 are of the same length, that isto say their free lower edges are in register.

For a more comprehensive understanding of the nature and objects of theinvention reference is had to the following detailed description of theillustrative preferred embodiment of the 1n- Cil vention, and to theaccompanying drawing in which: l

Fig. 1 is a plan view of a transfer set embodying the invention.

Fig. 2 is an end view of the article shown in Fig. 1 showing how thecarbon supporting members are interleaved, and

Fig. 3 is a verticalr section along the line III-III of Fig. l, lookingin the direction of the arrows. y

Referring to the Vdrawing for a detailed description of the embodimentof the invention there shown.' the transfer set comprises a holder sheetI, to the opposite marginal edges 2 of which are secured supportingblades 3 by any Suitable means as for example by stitchingA 4, which maybe; of textile thread, light flexible wire,` wire staples clinched attheir free ends, or like means. The upper end 5 of. the holder sheet isreinforced by the bar l' having opposite lateral extensionsV to formstops l for the purposev hereinafter explained.. A carbon sheet 8 is xedas by an adhesive, stitching, or other known means to the lower edge!!of each supporting blade 3.

Each blade 3 may be weakened along a line 3a adjacent and parallel tothe line of stitching 4 so that it may hinge easily about the holder I.The weakened hinge linesv3a may be made by creasing, scoring orperforating the blade material, or by bending so asi to crush or weakenthe fibers` in cases where the blades are made of fibrous material suchVas paper, cardboard, or leather. Each blade extends completely acrossthe carbon sheet 8 so that the latter is amply supporte-d over its fullwidthto ensure that the carbon sheets are held in correct register andWill withstand the action of drawngthe record sheets through the holderwithout displacement. The blades are shown in triangular form Vbutobviously they may be rectangular or otherwise shaped. Further it willbe understood that while the blades lare shown superposed they may beotherwise arranged with the carbon sheets superposed. The carbon sheets8 are of any desired length and are preferably arranged so that alltheir free ends l0 are in register.

As shown in the drawing; it is preferred to arrange the supportingblades 3 in superposed relation with each other and to attach them bymeans of the attaching device 4 to the opposite marginal portions of theholder or backing sheet I. kEach of the attaching devices 4 extendsalong one of the longitudinal marginal portions of the backing sheet iand is positioned at parts of the supporting blades which are overlappedwith the of the device, or

iranged in superposed relation with 'although it will be understood thatmore than marginal portions of the backing sheet, thusprovidinglongitudinal marginal reinforcements for said backing sheet. Asshown, there are two Vsupporting blades attachedat eachrof the oppositeYlateral edges ofthe backing sheet and ar"- each other,

bladesmay'b'e thus mounted .at each side in some cases only 'onesupporting blade may margin, These Vsupporting blades extend fromtheirsupporting Yattachments towardthe oppo,

Y' sheet are spaced at the same .distance from thel site edge of the setor device, the blades atY one side being thus interdigitatedwiththosefat the other side. supporting bladesfat each vsideof the' backingrear stop 1, and the forward edges 'of allof the bladesV aresubstantially flush withY each other. Y `When the carbon sheets to theseforward flushY edgesofthe supporting blades a thoroughly balancedassemblage is provided. The rearward edges of the` supporting blades 3vare preferably'inclinedaas' shown and theirearward margins of thelowerblades extend rearwardly slightly beyond the edges of theoverlying'blades so `asto provide readyacces's at all times to all ofthe blades soas to facilitate their manipulation as for .example whenthe device is beingA threaded into position with the record strips orwhen it is being removed from said record strips. s With such anarrangement, in. preparing the holder for use in typing, eachsupportingrblade 3 carryingfal carbon sheet 8 is swungclear of theholder'l in turn while the appropriate record strip or sheet I2.(seeFigf 3) is introduced be- Vneath it, Ythe .blades Y,then being'-turnedY down 5 dash lines inFig. 3.
